Yes, please do. >Regarding particular areas that I focused on - I would certainly say >the wash. I know people's opinions vary on this, but I cannot >imagine not washing the fuel. I wash three times always for about 2 >days each wash. It takes a bit of time, but the air pump just runs >off of a solar panel with a small battery bank - and I have the time >to wait. I also use 22% methanol - I haven't played around with >this much, so I am not sure how that volume is affecting my fuel. If it meets the standard then it's not affecting the fuel quality. I usually use 22% with single-stage (depending on the oil).

I will look into the link you sent James, and if anyone >else has any other ideas, I'd love to hear them. This below is from the NBB's database - I can't find the full report.

Rgds Keith Development of a Bio-Based Fuel for Turbine Engines http://www.biodiesel.org/resources/reportsdatabase/reports/gen/1998100 1_gen-106.pdf Title: Development of a Bio-Based Fuel for Turbine Engines Author(s): Baylor University, Department of Aviation Sciences Publication Date: Oct 1998 Summary: Baylor University's Renewable Aviation Fuels Development Center (RAFDC) has been involved for the last 18 years in the research, development, and certification of bio-based fuels as alternatives to the leaded gasoline used in general aviation's piston engines aircraft. RAFDC is currently involved in the development of a cleaner-burning alternative to today's turbine fuel used by commercial and military aircraft. Previous studies conducted at another institute on a ground test stand facility, have shown that a 10 to 20% blend of biodiesel in jet fuel can considerably reduce particulate emissions. The RAFDC program is testing blends of jet fuel with substantial percentages of bio-derived fuels to determine their performance and emissions. RAFDC's instrumented air pollution monitoring aircraft, a Beachcraft King Air, used to monitor air pollution, will be the flying test bed for the most suitable blend. After extensive ground tests, one of the two engines in this aircraft will be fueled by a blend of jet fuel with biodiesel and/or ETBE. At the conclusion of this phase, certification of the most suitable blend will be sought. Additionally, a nation-wide educational program will be promoted through the Baylow University/International Center for Aviation and the Environment's Clean Airports Program. Two major critical issues have prompted the development of such a program: local pollution at airports and the global environmental impact on climate change due to aircraft pollution. The American Lung Association is estimating that 64,000 premature deaths in the United States of America are due to particulate air pollution. Worldwide, there is a growing realization of the need to develop a clean burning alterantive to today's turbine fuels because of the effects that airliners are having on the relatively fragile atmospheric layers in which they operate. Particulate emissions from turbine engines have become a primary concern, especially in the tropopause where a large percentage of the airline traffic occurs, because of the atmosphere's sensitivity to pollution at these altitudes. The turbine engine fleet in the United States consumes approximately 16.2 billion gallons of aviation kerosene per year. If renewable, domestically produced fuels were blended into turbine fuel at a 20% level, the US would reduce its oil imports by 3.24 billion gallons a year. In addition to reducing our national trade deficit, this also would provide a large stimulus to US agricultural and domestic biomass fuel producers, creating new businesses and industries.
